METAL WINDOW SASH.

To all whom it may concern:

Be it known that I, DANIEL J. lWURNANn,

a citizen of the United States, and a rosident of Chicago Heights, in the county of Cook and State of Illinois, have made an Tnvention"Pertaining to a vMetal Window Sash, which invention is fully set forth in the following specification.

My invention relates to an all-metal 1 window sash, especially adapted for use in setting plate-glassstore fronts, and which may be used at the bottom of the glass only,

or at the bottom, sides and top, as occasion may require.

The object of my invention is to provide a metal setting for plate glass in which the glass is securely held between two metal parts in such manneras to afford simple and efiicien't means for adjusting and regulating W the pressure on the glass all along the setting and to avoid the vise-like grip usually present in store front settings of the allmetal type now on the market, and as a result to largely obviate the breakage of the plates of glass that commonly occurs due to the lack of uniformity in the pressure exerted at difierent points along the edges of the glass or. to excessive pressure exerted on the glass through such vise-like grip of 30 the holding parts, or both.

Another object of my invention is to provide a plate-glass setting that can be used either as a self-supporting setting without any backing of wood or other material, or 3% that can be used with equal advantage as a setting'in which the back member is supported by contact with the store front floor or with a molding used for that purpose, and one in which the presence or absence of 40 such backing member does not aifect 1 the adjustment and regulation of the gripping pressure on the glass. y

The invention is fully' described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in-which,-

Figure 1 represents a front elevation. of 59 the lower left hand corner of a plate of glass set in my new sash, portions ofthe glass and other parts being broken away to show details of the construction; Fig. 2 is a horizontal section on the line 22 of Fig. 1,

I looking in the direction of the arrows, and Fig. 3 is a perspective View of the inner bracket shownin diflerent cross-sections in Figs. 1 and 2.

Referring to the drawings, 1 represents the principal member of my sash, which is in the form of one or more'angle members extending entirely around the glass plate. one arm 1 of which is secured to the window sill or frame by means of screws 2 or in other suitable manner, and the other arm l extends at substantially a right angle to the sill or frame and carries at its outer end a backing part or flange 3 which extends forward fromthe arm 1 so as to contact with the inner surface of' the glass plate a short' distance from its edges. The part 3 is provided with a downwardly extending flange 3 and a raised portion 3", which acts as one side of a gutter to confine water of condensation or wash water between the part 3 and the glass plate, especially when the sash is used at the bottom of the window. In order to strengthen the part 3, metal fill Ing pieces 4 are inserted between the flange 3 and the part 1*. If desired, these hollow pleces {1 may be filled with button metal, lead or the like. I

In the construction shown, the parts of member 1 are made of one uniform sheet of metal, but where desired, the part 3 may be of lighter gauge and may be either integral with or attached to the other portions oft-he member.

At spaced intervals along the sash I provide brackets 5, which for convenience are held in place by the same screws 2 as are utilized for holding the member 1, although, if desired, separate means for holding the brackets 5 may be utilized, or the members 1 and 5 may be integral. One arm of the bracket 5 is provided with a hole 5 to accommodate the screw 2 and in line'therewith' another hole 5, which is adapted to fit over and cooperate with a raised portion 1 in the member 1, so as to assist inholding the bracket 5 in place. The outer edgeof this arm of the bracket is shown as projecting slightly beyond the corresponding edge of the member 1 for the face plate to bear against, although the edges of these parts may be in exact alignment, ifdesired. The other arm of the bracket 5 is provided with a screw-threaded opening 5 for a purpose hereinafter described, and the two arms of the bracket are connected by webs 5" for strengthening purposes.

t) represents the face plate, which may be of anysuitable design so long as the outer edge thereof is made to bear against one or both of the outer edges of the members 1 and 5, and the inner edge thereof is made to bear against the outer surface of the glass at a point approximately opposite to the flange 3.

The face plate 6 is held in place by screws '4' which pass through openings in the face plate and into the screw threaded openings 5 of the brackets 5. By turning these screws in the proper direction the face plate (3 is drawn towards the flange 3 and the glass is clamped therebetween in such manner as to avoid the vise-like grip on the glass that would result if the screws 7 were made to engage with the member 1 instead of the member 5 Both the members 1 and 5 being of sheet metal, they will give slightly under pressure, with the result that excessive pressure on the screw 7 will not be directly communicated to the glass, but will-be modified by the springing action of the parts 1 and I have found that by thus avoiding the direct vise-like action of the glass. holding members, the tendency to break the glass from uneven or excessive tension on the screws is avoided and breakage from these sources greatly reduced.

It will be obvious that when my sash is used at the bottom of a window, suitable drainage openings should be provided through the part 3 and the face plate 6, so that wash water or water of condensation accumulating in the gutter or part 3 may find its way to the sill or sill covering outside the setting.

lVhile my sash is especially useful in connection with heavy plate glass, it may also be used to advantage in the setting of sheet glass, and the use of the term plate glass iii the claims is intended to include sheet g ass.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a metal window sash, three substantially parallel sheet metal portions, the outer portions having edge flanges adapted to contact the glass and having their inner edges fixed with respect to the frame, and the middle portion having its edge next to the frame fixed and its outer edge free except for adjustableconnection with one of said outer portions.

2. In a metal window sash, three sheet metal portions substantially parallel with the glass and with each other, the two outer portions having edge flanges adapted to contact the glass and having their inner edges fixed with respect tothe frame, and the middle portion having its edge next to the frame fixed with respect to the two outer portions and having its outer edge adjustably connected with one of said outer port'ions'and free from the other outer portion.

3. In a metal window sash, an angle member having one arm fixed to the window frame and the other arm extending out from the frame substantially parallel with the glass and having a flange adapted to contact the glass, a smaller angle member having one arm fixed to the frame and the other arm substantially parallel with the glass and spaced from and free from the parallel portion of the first said member, a face plate having a flange along one edge contacting the glass opposite the first said flange and having its other edge adjacent the frame abutting the angle members, and an adjustable connection between the face plate and the free portion of the second said angle member.

4:. In a metal window-sash, an angle member having one arm fixed to the window frame and the other arm extending out from the frame substantially parallel with the glass and having a flange adapted to contact the glass, a smaller angle member nested within the first said member and having one arm fixed to the frame and the other arm substantially parallel with the glass on the same side with the parallel arm of the first said member and spaced from and free from the glass and the parallel portion of the first said member, a face plate having a flange along one edge contacting the glass opposite the first said flange and having its other edge adjacent the frame abutting the angle member, and an adjustable connection between the face plate and the free portion of the second said angle member.

5. In a metal sash, a member rigidly secured to a window frame and having a portion extending out from the frame approximately parallel with the glass, there being a flange along the edge of said portion adapted to contact the glass, a second member rigidly secured to the frame and having a portion extending out therefrom substantially parallel with the glass, a face plate having a flange at one edge contacting the glass opposite the flange of the first member and having its other edge contacting the affixed abutment along the frame, and an adjustable connection between the face plate and the outwardly extending portion of the second said member, said portion being free from other connection.

6; In a window setting for plate glass, an

inner member adapted to engage with the window frame and the inner surface of the glass near its edge, an outer face plate adapted to engage with the outer surface of the glass near its edge and to close the opening between the glass and the window 7 frame, an intermediate member between said inner and outer members and in engagement with the face plate near its outer edge, means connecting the face plate and intermediate me'mber'at a distance from the window frame and adapted to adjust said face plate and intermediate member towards and from each other.

7. In a window setting for plate glass, a

angle member, one arm of which is in engagement with the window frame or sill and the other arm provided with a glass engagwith a fixed portion of the window setting, a second angle member located between the face plate and said first mentioned angle member, one arm of which is rigidly secured in substantially parallel relation to the window frame or sill and another arm extending at an angle thereto and towards the glass, and means located at a distance from the window frame or sill and connecting the face plate and the outwardly extending arm of the second angle member and adapted to adjust said parts toward and from each other.

In testimony whereof. I have hereunto signed my name to this specification.
